Nearly nine in ten United States residents — 89% — correctly identify Japan as the nation who attacked the U.S. on December 7, 1941. Four percent believe another nation carried out the attack, and 7% are unsure.

Men (94%), Americans earning $50,000 or more annually (93%), and those 45 years of age and older (92%), are more likely to know the assailants in that infamous attack than are women (85%), residents making less than $50,000 a year (84%), and those under 45 years old (85%).
